Patented Aug. 6, 1935 UNITED STATES PATENT OFFICE 9 Claims.

This invention relates to hair waving or curling rods and moreparticularly to rods for use in connection with electrically heateddevices for enveloping the rods and hair wound thereon to produceso-called permanent waves.

While the rods herein shown and described may be used in various waysand to provide various types of waves or curls, they are particularlyadapted for use in so-called helical permanent 10 waving in which a lockof hair is spirally wound along the length of the rod and a heatingattachment is clamped over the hair and rod to provide the desiredpermanent curl or wave.

It is an object of the present invention to provide a permanent wave rodfor use in connection with the usual heating and steaming devices andwhich will produce a more natural wave than has heretofore beenpossible. It is well known that fine hair is very difficult to wave andit is necessary that it should be very carefully wrapped and stretchedduring its application to the rod.

It is therefore an object of this invention to provide a rod which maybe more easily held and turned during the wrapping process than are theusual rods, and in which there will be less tendency for the rod to slipin the fingers.

It is also an object to provide a rod having a cross-sectional contouras well as a longitudinal contour on which hair may be very snuglywrapped and stretched and in which the crosssectional contour of the rodis such that there will be little if any tendency of the rod to slip andallow the hair to loosen thereon during the winding or after it has beenclamped or otherwise enclosed in a heating device.

It is a further object to provide a rod which will produce a naturalwave when the hair is wrapped thereon in any of the various ways whichare common in the art; that is, the hair may be wrapped flat or with ahalf twist or threequarter twist or in any other desired manner, and

a particular curl will be retained until the permanent wave is obtained.

Further objects will be apparent from the specification and the appendedclaims.

In the drawing:

Figure 1 is a side elevation of a helical rod which is provided withhelical flutes or grooves, and

illustrates one embodiment of this invention.

Fig. 2 is a transverse section taken on a line corresponding to line2--2 of Fig. 1.

Fig. 3 is a side elevation of a tapered fluted rod and illustratesanother embodiment of this ll invention.

Fig. 4 is a transverse section taken on a line corresponding to line 44of Fig. 3.

Fig. 5 is a side elevation of a helical rod similar to that illustratedin Fig. l but without the helical flutes. 5

Fig. 6 is a transverse section taken on a line corresponding to line 6-6of Fig. 5.

Referring to the drawing in detail, the embodiment illustrated in Figs.1 and 2 comprises a tapered helical spiral rod adapted for use with theordinary steaming and drying devices and is provided with a handle ihaving the usual axial spindle 2 secured thereto and which is indicatedby dotted lines. An elongated tapered helical curling member 3 ismounted for rotation on the spindle 2 and is retained in positionthereon by means of the usual cap 4 which may be screwed onto the end ofthe spindle 2 in the usual manner. The curling portion 3 is usuallyrotatable, relative to the handle I, in one direction only, and isprevented from rotation in the opposite direction by means of the usualone-way clutch which is ordinarily mounted within the handle I. Thisgeneral type of construction is similar to those in common use andfurther detailed description of the parts, other than the curling member3, is believed to be unnecessary. The entire rod may, of course, beformed from a single piece of metal or other suitable material ifdesired.

The tapered member 3 forms a conical spiral; that is, it is notordinarily formed of a twisted rod but, instead, the helical axis of theconvolutions forms a conical spiral around the longitudinal axis of thecone, and the conical axis is preferably within the cross-sectionalcontour of any part of the rod, whereby the spindle 2 is always enclosedtherein.

The member 3 is also formed to provide spiral flutes or grooves 5between corresponding spiral lobes 6. This is particularly illustratedin cross section in Fig. 2. It will, of course, be understoodthat themember 3 may be made of comparatively thin tubing, if desired, or may beof a single piece of material as illustrated in Fig. 2 and provided witha longitudinal opening 1 through which the axial spindle 2 passes. Inusing this rod, the small end 4 is preferably placed adjacent the scalpand a lock of hair is spirally wound around the rod, substantially asindicated by the dot and dash line in Fig. 5, and then enclosed in asuitable heating means. Of course, other types of winding may be used ifdesired.

Figs. 3 and 4 illustrate a somewhat different embodiment of theinvention in which the curling member 3 is not in the form 0! a spiralbut is merely tapered toward the retaining member 4!. The member 3 is,howevenprovided with longitudinal flutes 8 .between corresponding lobess as illustrated. The shape of the rod in this embodiment provides avery pleasing wave, and the longitudinal flutes 8 prevent the slippingof the rods in the fingers and prevent loosening oi the hair.

Figs. 5 and 6 illustrate a conical spiral rod similar to the rodillustrated in Fig. lwith the exception that the spiral member 3* is notfluted as previously described, but, instead, is cylindrical in crosssection and may be formed from a sheet metal tube as illustrated in Fig.6. The dot and dash line In illustrates the usual method of winding thehair on the rod, although it will be understood that it may be wound inany desired manner.

The flutes l and 8 provide ventilation under the hair during thesteaming and heating operation and permit quicker drying, and in certaintypes of winding the spiral shape also assists in a like manner.

It will be understood that in using this invention, the hair is wound onthe rod and then steamed, and when dry retains the natural wave inducedby the shape of the rod, thus providing a particularly attractivepermanent wave having a characteristic appearance not obtainable withthe rods ordinarily used.

The device presents many advantages over prior structures and variousmodifications may be made without departing from the spirit of theinvention. It is desired, therefore, that the invention be limited onlyby the prior art and the scope of the appended claims.

Having thus described the invention, what is claimed and desired to besecured by Letters Patent is:

1. A permanent wave rod of the character described ior a heating andsteaming device comprising a handle, a spindle on said handle, a

conical spiral curling member mounted for rotation around said spindle,with said spindle completely enveloped by the convolutions, and meansfor retaining said spiral on said spindle.

2. A permanent wave rod for a heating and steaming device, comprising arigid elongated metal member having a plurality of longitudinal flutestherein with rounded lobes therebetween,

said flutes being of suflicientwidth to cause permanent undulations inthe permanent waves of hair wound and steamed thereon.

3. A permanent wave rod for a heating and steaming device, comprising arigid elongated metal member having a plurality of longitudinal lobesthereon forming substantially V-shaped flutes therebetween, the verticesof said lobes being sufliciently spaced to cause permanent undulationsin the permanent waves of hair wound and steamed thereon.

4. A permanent wave rod for a heating and steaming device, comprising arigid elongated tapered metal member longitudinally lobed in crosssection, said lobes tapering in accordance with the taper of the rod andbeing sufliciently spaced to form permanent undulations in the permanentwaves of hair wound and steamed thereon.

5. A permanent wave rod for a heating and steaming device, comprising atapered metal rod forming a high pitched spiral with the axis of the rodentirely within any cross sectional contour.

6.
